Product Description



China Arrester 100ka Power Surge Arrester

By use
(1) Switching type lightning protector
Its operating principle is when there is no transient overvoltage presented as a high impedance, but once the response to lightning transient overvoltage, its impedance is suddenly changed to a low value, allowing the lightning current to pass. Devices used for such devices are: discharge gaps, gas discharge tubes, gate transistors, etc.
(2) Voltage limiting type lightning arrester
Its working principle is that when there is no transient overvoltage for high impedance, but with the increase in surge current and voltage impedance will continue to decrease, its current-voltage characteristics are strongly non-linear. Devices used for such devices are: zinc oxide, varistors, suppression diodes, avalanche diodes and other lightning protection devices are mostly voltage limiting type.
(3) shunt type or choke type lightning arrester
Shunt type: parallel connection with the protected equipment, the lightning impulse is presented as low impedance, while the normal operating frequency is presented as high impedance.
Choke type: in series with the protected equipment, the lightning impulse presents a high impedance, while the normal operating frequency presents a low impedance.
Devices used for this type of device are: choke coils, high pass filters, low pass filters, 1/4 wavelength shorters, etc. [1] .
By lightning protection level
Class I lightning protector: generally nominal above 30KA. There are switching type and voltage limiting type.
Level 2 lightning protector: generally nominal between 15 - 20KA. All voltage limiting type.
Third-level lightning arrester: generally nominal between 5 - 10KA, are voltage limiting type.
Role characteristics editor broadcast
Lightning protector is used to protect various electrical equipment in the power system from lightning overvoltage, operating overvoltage, frequency transient overvoltage impact and damage to an electrical appliance. The main types of lightning arresters are protection gaps, valve-type lightning arresters and zinc oxide lightning arresters. Protection gaps are mainly used to limit atmospheric overvoltage and are generally used to protect incoming sections of distribution systems, lines and substations. Valve type lightning arresters and zinc oxide lightning arresters are used for substation and power plant protection, and are mainly used to limit atmospheric overvoltage in 500KV and below systems, and will also be used to limit internal overvoltage or as backup protection for internal overvoltage in ultra-high voltage systems.

This series of surge protector device(SPD)is suitable for new energy solar power generation system, and the maximum continuous working voltage is DC500V, 800V, 1000V, 1200V. The installation position is in the DC power supply system to protect indirect lightning current, direct lightning current or other transient overvoltage.




Surge protective device, protect against lightning surge voltages in solar system (photovoltaic power supply system).
These units must be installed in parallel on the DC networks to be protected and provide common and different modes protection. Its installed location are recommended at both ends of the DC power supply line (solar panel side and inverter/converter side), especially if the line routing is external and long.
High energy MOVs equipped with specific thermal disconnectors and related failure indicators.

If I'm interested in your DC SPD when I can receive your quotation and detail information after send the enquiry?

All your enquiry will be replied in 24hours.



Your DC SPD seems perfect but what's the difference between you and other suppliers? Because I find some cheaper price from others!

Our DC SPD is special for Solar system all the parts in the SPD are high quality customized. Not all the SPD are DC SPD!



Can I get a sample before the order because I really don't how is your DC SPD quality?

Of course! We also think sample order is the best way to build the trust.And in our company we offer free sample service! Please send the enquiry to us and get the free sample!



Do you have a catalogue? Can you send me the catalogue to have a check of all your products?

Yes, We have product catalogue. Please contact us on line or send an Email to sending the catalogue.



I need your price list of all your products, do you have a price list?

We do not have a price list of all of our products. Because we have so many items, and it is impossible to mark all of their price on a list. And the price are always changing because of the producing cost. If you want to check any price of our products, please feel free to contact us. We will send offer to you soon!
